Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Have no significant medical history or examination findings related to the foot to be treated, which in the investigator's opinion, would make the participant unsuitable for study intervention administration.
* Have a diagnosis of plantar fasciitis for ≥6 months, which has not responded to conservative therapies. Conservative therapies may include rest, physical therapy, splinting/bracing, orthotics, icing, physiotherapy, acetaminophen, corticosteroids, or nonsteroidal anti-inflammatory drugs (NSAIDs).
* Have current foot pain due to plantar fasciitis.

Exclusion Criteria

* Has any musculoskeletal, neuromuscular, neurosensory, other neurological or related disorder that affects the participant's use of his/her feet and/or would impair his/her completion of study assessments as determined by the investigator either due to the disorder or due to pain.
* Has a clinically meaningful laboratory abnormality.
* Has a body mass index ≥35 kilograms per meter squared (kg/m\^2).
* Has a known bleeding disorder, which, in the investigator's opinion, would make the participant unsuitable for enrollment in the study.
